About Postfix

What is Postfix? It is Wietse Venema's mailer that started life as an alternative to the widely-used Sendmail program.

Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.

About Postfix Wiki

Postfix Wiki tries to collect all available documentation on Postfix. This seems like a big task, and without your help it's going to be.
So... Type along! :)

Postfix Manuals and Documentation

The online documentation at www.postfix.org is for the current official release. Postfix 2.x users should find the documents largely applicable to their systems, with features that require later releases noted in the tutorials or configuration parameter reference guide. Postfix 1.x users will more frequently find that the recipes in the tutorials require modifications or that the features described are not available.

When in doubt consult the documentation that is included with the source code of your release. This is typically installed with binary software packages. The location of the HTML documents is recorded in the "html_directory" configuration parameter. Postfix 1.x configuration samples were also found in the "sample_directory".

The documentation of each configuration parameter is at www.postfix.org/postconf.5.html#parameter_name

Keep it simple initially, don't build the complete configuration in one go, add a few features at a time and test. Use simple indexed files first, get used to the various tables that drive Postfix, and only then consider using LDAP, MySQL, PostgreSQL, ... to configure the tables:
